The invention discloses a device for storing etching liquid. The device comprises a base (1), a servo motor (2) and a storing tank (3), wherein the servo motor (2) is arranged vertical to a vertical column B (5) and fixedly mounted on the vertical column B (5); a rotating shaft I (6) and a rotating shaft II (7) are respectively arranged at two sides of the storing tank (3); the other end of the rotating shaft I (6) is mounted on a vertical column A (4) by rotating; the rotating shaft II (7) is connected with the output end of the servo motor (2); a cavity (8) for storing the etching liquid is formed in the storing tank (3); a liquid inlet (9) and a liquid outlet (10) are respectively formed in the top part and the bottom part of the storing tank (3) and are both communicated with the cavity (8); a plurality of air inlets (11) communicated with the cavity (8) are formed in two sidewalls of the storing tank (3). The device has the beneficial effects of being small in manufacturing cost, simple to operate, and capable of effectively avoiding the etching liquid from depositing.
Description
Technical field
The present invention relates to the technical field, particularly a kind of device of splendid attire etching solution that stir etching solution.
Background technology
At present, circuit card in etching process, the copper bar on etching solution open circuit potential plate, along with the continuous dissolving of copper product, the proportion of solution constantly raises, after proportion exceedes certain value, the etching solution of auto-compensation ammonium chloride and ammonia-water systems, adjustment proportion is to suitable scope.General specific gravity control is at 18 ~ 240Be.The pH value affecting etching solution of solution pH value should remain between 8.0 ~ 8.8.
When the pH value of etching solution is reduced to below 8.0, unfavorable to metal resist layer on the one hand, on the other hand, copper in etching solution complexing can not become ammoniacal copper complex ion completely, and solution there will be precipitation, and forms sludge at bottom land, these precipitations can form sclerderm on the heaters, may well heater be damaged, also can block pumps and nozzle, cause difficulty to etching.Only have constantly stirring etching solution that etching solution is constantly moved, precipitation is there is to prevent solution, when needs use etching solution etched circuit board, releasing etching solution, at present, great majority adopt agitator to stir etching solution, but this agitator structure is complicated, agitating vane solution on it is etched corrosion, does not promote the use of.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of compact construction, low cost of manufacture, simple to operate, can effectively avoid etching solution to produce the device of splendid attire etching solution of precipitation.
Object of the present invention is achieved through the following technical solutions: a kind of device of splendid attire etching solution, it comprises support, servomotor and storage tank, described support is provided with the column A perpendicular to support and column B, described servomotor arranges perpendicular to column B and is fixedly mounted on column B, the both sides of described storage tank are respectively arranged with rotating shaft I and rotating shaft II, rotating shaft I and rotating shaft II is symmetrical arranged, the other end of rotating shaft I is rotatably mounted on column A, rotating shaft II is connected with the output terminal of servomotor, the die cavity for splendid attire etching solution is provided with in described storage tank, the top of storage tank, bottom is respectively arranged with fluid inlet, liquid outlet, fluid inlet is all communicated with die cavity with liquid outlet, two sidewalls of described storage tank are provided with multiple inlet mouth be communicated with die cavity.
It also comprises controller, and described controller is connected with servomotor.
Described fluid inlet and liquid outlet place are all connected with stop valve.
The present invention has the following advantages: two sidewalls of storage tank of the present invention are provided with multiple inlet mouth be communicated with die cavity, in storage tank, clean high-pressure air is passed into through inlet mouth, high-pressure air promotes etching solution in die cavity, does irregular to-and-fro movement, and rotate in conjunction with driven by motor storage tank, effectively avoid etching solution and produce precipitation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1-support, 2-servomotor, 3-storage tank, 4-column A, 5-column B, 6-rotating shaft I, 7-rotating shaft II, 8-die cavity, 9-fluid inlet, 10-liquid outlet, 11-inlet mouth, 12-stop valve.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of device of splendid attire etching solution, it comprises support 1, servomotor 2 and storage tank 3, described support 1 is provided with the column A4 perpendicular to support 1 and column B5, described servomotor 2 arranges perpendicular to column B5 and is fixedly mounted on column B5, the both sides of described storage tank 3 are respectively arranged with rotating shaft I6 and rotating shaft II7, rotating shaft I6 and rotating shaft II7 is symmetrical arranged, the other end of rotating shaft I6 is rotatably mounted on column A4, rotating shaft II7 is connected with the output terminal of servomotor 2, the die cavity 8 for splendid attire etching solution is provided with in described storage tank 3, the top of storage tank 3, bottom is respectively arranged with fluid inlet 9, liquid outlet 10, fluid inlet 9 is all communicated with die cavity 8 with liquid outlet 10, described fluid inlet 9 and liquid outlet 10 place are all connected with stop valve 12.Two sidewalls of described storage tank 3 are provided with multiple inlet mouth 11 be communicated with die cavity 8.
It also comprises controller, and described controller is connected with servomotor 2, and control startup or the closedown of servomotor 2 by controller, can also control the rotating speed of servomotor 2, operation is very easy simultaneously.
Working process of the present invention is as follows: the stop valve 12 first opening fluid inlet 9 place, in die cavity 8, inject a certain amount of etching solution close this stopping valve 2 subsequently, control the startup of servomotor 2 again, servomotor 2 drives rotating shaft II7 to rotate, rotating shaft II7 drives storage tank 3 to rotate, thus drive etching solution to rotate, in storage tank 3, pass into clean high-pressure air through inlet mouth 11 simultaneously, high-pressure air promotes etching solution and do irregular to-and-fro movement in die cavity 8, and in conjunction with rotary motion, effectively prevent etching solution and produce precipitation.When etching solution will be taken, only need close servomotor 2, open the stopping valve 12 at liquid outlet 10 place, etching solution is released.
The above is only the preferred embodiment of the present invention, be to be understood that the present invention is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from the spirit and scope of the present invention, then all should in the protection domain of claims of the present invention.
